Medium-Power RF Transistor for Industrial & Defense Applications
Brand: AIMRSE
This is a high-performance, wide-bandwidth, multi-channel transceiver integrating four RF-sampling transmitter chains and four RF-sampling receiver chains. The device operates at frequencies up to 7.4 GHz, supporting direct RF sampling in the L-, S-, and C-band frequency ranges without requiring additional frequency conversion stages. Enhanced density and flexibility enable support for high-channel-count, multi-mission systems.
The TX signal path supports interpolation and digital upconversion options, using either a single-band or dual-band digital upconverter (DUC) to provide up to 400 MHz of signal bandwidth per TX path. The DUC output drives a 12 GSPS DAC (digital-to-analog converter), with a hybrid-mode output option enhancing operation in the second Nyquist zone. The DAC output includes a variable gain amplifier (TX DSA) with a 40 dB range, 1 dB analog steps, and 0.125 dB digital steps.
Each receiver chain includes a digital step attenuator (DSA) with a 25 dB range, followed by a 3 GSPS ADC (analog-to-digital converter). Each receiver channel features an analog peak power detector and various digital power detectors to assist external or internal autonomous automatic gain controllers, as well as an RF overload detector to provide device reliability protection. Flexible decimation options support the use of one or two digital downconverters (DDCs) to optimize signal bandwidth up to 400 MHz.
